You started off very well. You identified the given and the pair of congruent sides.
Statement Reason
3. m<POM = m<NMO Alternate Interior Angles
4. m<NOM = m<PMO Alternate Interior Angles
5. ΔPMO ≅ ΔNOM ASA
6. MP ≅ NO CPCTC
Reasoning for statement 3: This is because MN ║PO and MO acts as a transversal.
Reasoning for statement 4: This is because MP ║NO and MO acts as a transversal.
Answer:
The length of the triangle is 3x given
The no of sides is 3x 3x 3x so 3x+3x+3x= 180
9x=180 x= 20
3x =3*20=60
3x=3*20=60
3x=3*20=60
All of 4's value is hundreds, tens, and ones.
